One object'ot the invention is to provide clamp comprising ine nbers which may be sea ctree about the-end eta rod and the endso f a loop secured between such ;n embers in such way that thero-d and. loop 'may' be reversed desired. r

rlincther object theinvention is to .pror'de clamp com rising a pair. of members arranged so as .to clampei'ther.a'broken or. straight rod or an upset red as is required. A still further object of the invention is to provide a pull loop having its ends secured in the clamp against displacementand' arranged to be reversed whenthe clamp is reversed. I v i A particular featme of the invention is to '1 vide the clamp with fiat endfaces so that eich'c face may be placed against an upright support; while an additional feature resides in a handle whereby the clamp may be safely held by the workman. j A construction designed to carry out the in arecontiguous to the upper and lower edges of each clamp member. At each socket and notcha reinforcing boss 18 is cast on thememr, the bottom of the notch being flush with sunk below the notch.

At the end oi' each groove 19 nlai'ged concent'ic seat 19, while a p y seat 2 "is formed at the outerendlof each groove 20.. 7 7 I Two pairs of bolts 21 are passed through apertures 22 in the membersoneach side of the grooves, 19 ,and, and betweenv the vention will be hereinafter described, tcgethgrooves 15". The heads of these bolts are er v ith other features of the invention. countersunk 1n the outer surface of the mem- The invention will be more readily under s ood from a reading of the following speciiication and by reference to the accompanying drawings, in which an exampleot the invention is shown and wherein:

Fig. l is a planview of a clamp constructed in accordance with the invention and showing a. portion of a rodconnected therein,

10, whereby said clamp members are securely fastened in position and may be readily disconnected.

i U-shaped pull 1o0p24l is provided at its inner ends with upset heads 25 and outwardly directed lugs 26. The heads engage in the socket l6 and the lugs are received in the :25 Fig. 2 is an elevation of the same,

It will be seen that the loop red and a pullloop in position-therein, I may be inserted between the members so as to project from either end of the grooves 15.

Fig. 5 is an end view the clamp, and out o'lithe loop and thus not only make for efii- 6 is a cross-sectional view taken on cienc gbut for safety as well.

in 3 I have shown a rod A provided with circular head B engaging in the seat It the rod was upset under the head .e line o-G of Fig. 2.

in the drawings the numeral 10 design a. clamp n'iemher 11 a 'complementary clamp member, each composing substantially one-half of the clamp. Each clamp member is provided with laterally extending vertical ribs or flanges 12 at each end, whereby said members are tormedwith flat end faces 13 for engaging an upright support; The member 11 is provided at its central portion with an arched handle let by which the clamp may be supported in the hand of the workman, thus making for safety and convenience.

Each member 10 and 11 is provided near its or upset and not provided with a head, it

ly the rods break and in such cases the clamp .iembers may be separated and the loop reversed so that the straight end of the rod A may inserted in the grooves 15, as is shown in Fig. 4. WVhen the nuts 23-ar'e tightened the clamp members will be tightly fasparts can not become dislodged.

The clamp is compact and has sufiicient extend at right-angles to the flanges 12 and nner'surface ofthe boss and the socket Each 'clampjmember has atjits center and,

her 11 and nuts 23 screwed onto the ends of the bolts engage the outer side of the member would fit the flared grooves 20. Frequent-' toned on the rod and pull loop so that these nearest 1 groove 20 extending from the inner end'ot' i strength,owing to the flanges 12 and the bosses 18, to stand up under heavy Work. The flat faces 13 permit the clamp to be firmly supported against an upright flat surface. The handle 1- enables the Workman to easily grasp the clamp and hold it, particularly when dis-- connecting the pull loop 24: from its connection. It is merely necessary to remove the four nuts 23 to disassembled the clamp members, and by reason of said nuts the said clamp may be tighened to the proper degree.

Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the scope of the appended claims.

What I claim, is: V

1. A combination clamp comprising a pair of clamp members having sockets and rod grooves, a pull loop having heads engaging in the sockets, bolts securing said members together and for clamping them about a pull rod, and an arched handle on one of the clamp members for supporting the clamp.

2. A combination clamp comprising a pair of clamp members having sockets and rod grooves, a pull loop having heads engaging in the sockets, and bolts securing said members together and for clamping them about a pull rod, said clamp members being reversible for receiving a broken rod and provided with fiat supporting end faces.

3. A combination clamp comprising a pair of clamp members bolted together, and a pull loop having its ends secured between the clamp members, said clamp members having longitudinal rodreceiving grooves having rectilinear and flared portions for receiving straight and upset rods.

4. A combination clamp comprising a pair of clamp members bolted together, and a pull loop having its ends secured between the clamp members, said clamp members having longitudinal rod receiving grooves having rectilinear and flared portions for receiving stra ht and upset rods, said loop being reversible in said members, whereby a rod may 6. A combination clamp comprising a pair of clamp members bolted together, each member having grooves contiguous to its top and bottom bisected by sockets, and a pull loop on gaging in the said grooves and having heads engaging in the sockets of said members, the

clamp members having reinforcing bosses at the sockets and also notches at said bosses,

said loop heads also having lugs engaging in said notches.

In testimony whereof I affix my signature.
